Abstract

A traffic cone includes a cone-shaped body and a base. The cone-shaped body has a hole in the top and a connecting circumference formed in a lower end. The connecting circumference is provided with a large number of upright bars spaced apart equidistantly, and a through hole formed between every two neighboring bars. The base is formed in a mold that an already formed cone-shaped body is placed in advance before the base is formed so the base may be combined integral with the cone-shaped body after the base is finished. Then the base completely wraps around and hides the connecting circumference of the cone-shape body, with the through holes of the connecting circumference filled up totally by the base.

 DETAILED DESRIPTION OF THE PREFERRED EMBODIMENT
A first embodiment of a traffic cone in the present invention, as shown in FIGS. 1 to 6, includes a cone-shaped body 1 and a base 2 as main compoments combined together.
The cone-shaped body 1 has a tapered-up outer surface 10, a hole 11 formed in the top for inserting a warning flag, a warning light or the like, an L1 portion of the wall 100 having a thickness D1 larger than that D2 of an L2 portion of the wall 100 as shown in FIG. 2, and a connecting circumference 12 formed in a lower end and provided with many upright bars 120 extending up and down the connecting circumference 12 and spaced apart equidistantly with a through hole 121 formed between every two neighboring bars 120 as shown in FIG. 3.
The objective of the provision of the different thickness for the L1 and the L2 portion of the wall 100 is for convenience of stacking a number of the traffic cones, because the L1 portion of an upper traffic cone can have a gap (S) between its inner surface and an outer surface of a lower traffic cone after a number of the traffic cones are stacked. Then this gap (S) can facilitate every two neighboring traffic cones to separate from each other after stacked.
The base 2 is in a mold that an already formed cone-shaped body is placed in advance in, wrapping around completely the connecting circumference 12 of the cone-shaped body 1 to become integral with the cone-shaped body 1 hiding completely the circumference 12 and filling up the through holes 121, as shown in FIGS. 5 to 8. Further, a connecting surface 20 of base 2 hiding the connecting circumference 12 has a different color from that of the cone-shaped body 1.
Thus the traffic cone according to the invention has the base with a large weight to let its gravity center located in the base, so the traffic cone may not so easily fall down even in case of strong wind. In addition, the cone-shaped body 1 and the base have different colors from each other, with the base 2 with the deep or dark color not liable to look dirty. Apart from that, the base 2 can be made of recycled plastic to save its cost for the benefit of buyers. Asides that, the base of the traffic cone can be separated from the cone-shaped body by the force of a vehicle in case the vehicle should run over the traffic cone, not to get stuck with the chassis of the vehicle to keep safety of traffic.
FIGS. 9 and 10 show a second embodiment of a traffic cone in the present invention, which has a minor disparity from the first embodiment. The cone-shaped body 1A in the second embodiment is provided with plural continual annular recesses 10A on its outer surface, and a reflective paper can be adhered on the annular recesses 10A, located a little lower than the tapered outer surface 10 so the reflective paper may not rub with the ground even the traffic cone should fall down, prevented from getting wear and tear and able to keep the original effect of light reflection. In addition, the inner surface 100 of the cone-shaped body 1A is provided with an annular ridge 101 with a large thickness D3 in a lower portion, so every two neighboring traffic cones stacked may have a gap S1 as shown in FIG. 10 between them to permit them easily separated from each other. Then a large number of the traffic cones can save big space in storing by stacking one by one to a very large height.
The cone-shaped body 1A has the same connecting circumference 12A as that 12 in the first embodiment.
The base 2A is formed in a mold that an already formed cone-shaped body 1A is placed in advance, as in the same way of the first embodiment, also wrapping around the connecting circumference 12A to combine the cone-shaped body 1A integral with the base 2A as shown in FIG. 9. Thus the second embodiment has the same function and effect as the first embodiment, with its gravity center located in the base 2A.
Next, FIGS. 11 and 12 show a third embodiment of a traffic cone in the present invention, which has almost the same structure, except a minor difference. The cone-shaped body 1B has a connecting circumference 12B with an annular wall 12B0 extending down in the lower end. The base 2B is formed in a mold that an already formed cone-shaped body 1B is placed in advance, with the annular wall 12B0 of the connecting circumference 12B fused by heat with the base 2B to form the cone-shaped body 1B combined integral with the base 2B as shown in FIGS. 11 and 12. Then the third embodiment has the same function and effect as that of the first embodiment, not easily falling down with the gravity center located in the base 2B.
While the preferred embodiments of the invention are described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
